How do you reconcile that with this explicit statement on the web page
that was cited by Kazimier Gawrzyjal:

 This Part 2 of EN 50332 specifies methods of measuring the matching
values for the use of personal music players and headphones/earphones
defined for the use with those...

No way is a car audio system a 'personal music player'.

I would advise GREAT caution in attempting to widen the scope of the
standards by inference, because we will get back to everything,
including desktop computers, being considered 'portable music players'.
